NOTES
1
Ratings shown are net capacities which include a deduction for indoor fan motor heat.
2
On the figure the mark with show the max, onces at standard conditions.
On the figure the mark with show rated capacity and rated coefficient of power input.
However the max. Capacity is not guaranteed ecxept at standard condition.
3
SHC* is based on each EWB and EDB.
SHC= SHC correction for other dry bulb.
= 0.02xAFR (m
3
/min.)x(1-BF)x(DB*-EDB)
Add SHC to SHC*.
4
Capacities are based on the following conditions.
Outdoor air: 85% RH. However, the condition
rated capacity is 7°C DB/6°C WB. (heating)
Corresponding refrigerant piping length
: 5.0m
Level difference
: 0m
5
Coefficient of power input is the percentage when the rated value is defined as 1.00.
6
The value contains less than 5% error acording to indoor unit type.
7
Heating performance include the drop of frost formation.
8
Air flow rate and (BF) are tabulated below.
9
Rated power input of each model is tabulated below.
